DC-DC converters are very important in today’s energy world. In a nutshell, they convert a DC voltage to another voltage level while maintaining very high efficiency. They are also used to isolate and protect sensitive electronics from power supply spikes and other power transients.

The TVN 5-0913WI DC-DC converter from PowerIntegrations is a highly integrated, high-performance dc-dc conversion module. It is specifically designed to facilitate the maximization of available space between the input and output terminals of three-phase systems. It operates from DC input voltages ranging from 12-510Vdc, and then regulated outputs up to 513Vdc. This makes it perfect for use in a variety of applications, such as motor drives, power supplies, optical networking, and industrial automation.

The TVN 5-0913WI includes an on-chip phase-shift controller, as well as an integrated power MOSFET and an extremely low EMI switching network. It features low-jitter pulse-width modulation (PWM) control, allowing it to operate in discontinuous conduction mode (DCM) at the high levels of efficiency necessary for reliable design. The switching frequency is programmable between 100kHz and 200kHz, allowing the optimization of switching losses and electromagnetic interference (EMI).

The hardened I/O pins on the TVN 5-0913WI make it suitable for use in harsh environments, such as automotive and commercial vehicle applications. The controller also features several protection and monitoring functions, including soft-start, temperature shutdown, over-current protection, short-circuit protection, and under-voltage lockout. In addition, the TVN 5-0913WI includes an integrated 500kHz voltage error amplifier and a dynamic current preview function.

In addition to providing high efficiency and excellent environmental protection, the TVN 5-0913WI is simple and cost-effective. The two-level, three-phase buck converter eliminates the need for complex gate drivers and external filters, saving both time and board space. The device also supports remote on/off logic control, allowing its operation to be toggled from a long distance. Of course, it also features low output ripple, no noise production, low-power consumption, and low standby power.

The TVN 5-0913WI offers a wide range of potential applications, ranging from motor drives and power supplies to optical networking and industrial automation. Its longevity and efficiency make it suitable for critical renewable energy applications, such as wind turbine and solar power converters. Despite its small size, the TVN 5-0913WI boasts immense power handling capabilities, with a maximum current of 200A and a maximum power of 800W.

In summary, the TVN 5-0913WI from PowerIntegrations showcases the best of modern dc-dc converter technology. It’s highly efficient, with a high performance integrated phase-shift controller and low-jitter pulse-width modulation control. It is also durable and cost-effective, reducing complexity and board space. With a wide range of potential applications, the TVN 5-0913WI may just be the perfect choice for your next power supply project.
